vTiger customization Quote / Invoice + include 1 added field

Looking for a vTiger / sugarcrm programmer. Need to customize quotation to include more fields to display on quotation report. There will be a few calulations to be applied. Please see attached pdf for sample output of the invoice/pdf. Quotation is for: - one time products (need button to indicate for product input form) - recurring monthly products (need button to indicate for product input form) Note <-- added fields within existing forms/modules: 1.) Customer detail form will need to include extra field that states: Currently Monthly Phone bill: <-- this information will be used for saving calculation on quote 2.) prodcuts need extra classification field: Monthly Recurring or One time. this field is used to specifiy within the quote the placement / calculation of the one time charges vs recurring fees.
